RNA Editing of Cytochrome Oxidase Subunit III in Sunflower Mitochondria.
Direct sequencing of cytochrome oxidase subunit III (coxIII) mRNA with a specific primer confirms RNA editing in sunflower (Helianthus annus) mitochondria. Six instances of mRNA editing could be verified, one of these specific to this species. All the editing events involve C to U transitions in the coxIII mRNA causing codon changes that lead to amino acids better conserved in evolution than th...
متن کاملAnalysis of Hereditary Elliptocytosis with Decreased Binding of Eosin-5-maleimide to Red Blood Cells
Flow cytometric test for analyzing the eosin-5-maleimide (EMA) binding to red blood cells has been believed to be a specific method for diagnosing hereditary spherocytosis (HS). However, it has been reported that diseases other than HS, such as hereditary pyropoikilocytosis (HPP) and Southeast Asian ovalocytosis (SAO), which are forms in the category of hereditary elliptocytosis (HE), show decr...
متن کاملStability of eosin-5'-maleimide dye used in flow cytometric analysis for red cell membrane disorders
BACKGROUND The eosin-5'-maleimide (EMA) binding test using flow cytometry is a common method to measure reduced mean channel fluorescence (MCF) of EMA-labeled red blood cells (RBCs) from patients with red cell membrane disorders. The basic principle of the EMA-RBC binding test involves the covalent binding of EMA to lysine-430 on the first extracellular loop of band 3 protein. METHODS In the ...
متن کاملRapid flow cytometric test using eosin-5-maleimide for diagnosis of red blood cell membrane disorders.
Conventional diagnosis of hereditary red blood cell (RBC) membrane disorders, in particular hereditary spherocytosis (HS), is labor intensive, time consuming and requires at least 2 ml of blood, which might be impractical in neonatal period. We evaluated the use of eosin-5-maleimide (EMA), a dye that reacts covalently with lysine-430 on the first extracellular loop of band 3 protein, for rapid ...
متن کاملActivation of beef-heart cytochrome c oxidase by cardiolipin and analogues of cardiolipin.
Beef-heart cytochrome c oxidase lacking endogenous lipids can be prepared by cholate-mediated exchange with dimyristoylphosphatidylcholine (Powell, G. L., Knowles, P. F. and Marsh, D. (1985) Biochim. Biophys. Acta 816, 191-194). These preparations retained practically no endogenous cardiolipin (less than 0.19 mol cardiolipin per mol of oxidase) but in Tween 80 they retained unaltered electron t...
